When developing MTS Artguide app I needed to use calendar view. While there are existing implementations (Kal and TKCalendarMonthView from Tapku Library, they are quite limited. In particular they both replicate styling and functionality of iPhone Calendar app and there is basically no easy way to adjust them. In addition to this – only portrait view is supported in them. And I absolutely had to support landscape mode.

So I developed my own control. ios-calendar is a stylable month calendar view for use in iPhone applications. It uses Three20 framework heavily, especially for styling.
